Application m August 16, 1926. Serial no. 129 ,47a

This invention relates generally to im: proveinents in casement windows of netal or wood construction and particularlyhto windows having vertically hinged sashg members adapted for horizontal sliding movement in the frame, one sash of which is adapted for horizontal swinging movement relative to the other in such manner that the maybe foldeditogether, andcentrally positioned in the ii'rameto provide air (inlet spaces upon opposite sides thereof. 7 s

The invention contemplates the use of a pairofhinged shutters having screens, the said shutters being arranged at opposite l6 sidesof thei'rame in such manner that when the sashanembers are centrally positioned relative tothe frame and folded together as above described the shutters may be swung inwardly against opposite sides ofthe folded saslrmembers to form screened ventilation openings, the shutters being additionally provided witlrdeflecting means adapted to break up the air currents entering the room therethrough. y i it t u 5 t The primary object of the invention is the provision of a window of the class designated, that is of extremely simple construcf-rame without the use of any hardware other 8 thania lockingmeans therefor. i

Another object of the invention is the provision of a window having slidable sashmembers out the class describedthat may be readily positioned centrally of the frame to provide easy access to -the"glass surfaces of both sash-members from the inside ofthe room for cleaning purposes. a

Another andmostirnportant object of the invention is the provision of a casement window having hinged sashunembers so farrangedthatthey may be moved to a central position in the frame and folded together, thus providing screened openings at both sides thereofforthe ingress of fresh air to the room. t v p a Other objects and advantages of the invention will ap ear with. reference to the subjoined speci cation and accompanying two sheets of drawings in which:

Referring with greater particularity to the drawings in wh ch a preferred embodiment of my invention has been shown, (1) 1n a general way designates the window frame consisting of the sill (2), stiles (3) and (4), and stile header (5), nary construction. a

A pair of centrally hinged panels or sash-members (6) and (7) having vertically disposed hinges (8) and (9) are set in the frame (1) and normally extend between the stiles (3) and (4) thereof, said sash members and frame being preferably constructed of wood as shown, but it is to be understood that metal construction may be used if desired. The left hand sash in this instance being provided at its upper edge with a guide strip (10) and at its lower edge with a hardwood guide strip (11,) mortised into the lower edge as indicated at (12) and having a projecting tongue (13) adapted all of ordiing mounted to form a slidable fit in the sill groove (14) of the sill (2), the up er strip (10) thereof being adapted to sli ably fit in a-groove (15), Figure 3, formed in the under face of the stile header (5) of the frame.

The sash (7) forms the sill (2), stile (4), and stile header (5), and is hinged to the sash (6)' in such manner that it may be swung outwardly in a horizontal plane and folded back against said sash (6) so that both will lie fiattogether asshown in Figure 2. The strip (16) extends all around the inside surfaces of the frame and provides a stop against which the free edges of the hinged sash (7) abut and forms a weather strip for both sash-members (6) and (7) when the said members are in closed position.

The-sash (7) is providedat its free side edge (17) with a spring catch (18) adapted toengage in the groove (19) formed in the stile (4) of the frame (1) to hold the sashmembers in locked position relative to said frame.

The shutters (20) and (21) are hinged to the inner edges of the face plates of the frame (1) by pairs of hinges (22) and (23) and normally lie fiat there against when in their open positions, said shutters being of sufficient width to close the open s aces (24) and (25) formed at opposite si es of the folded sash-members when said members are centrally positioned in the frame, and adapted to overlap oppositeside edges of the sash (7) when swung to the posit-ion shown in Figures 2 and 3. The shutters (20) and (21) are of the same size and construction and each consist of a frame (26) having an outer screen covering (27), Figure 9, and inner spaced slats (28) having air inlet openings (29) there between, said slats forming draught deflectors adapted to defleet the incoming air currents upwardly toward the ceiling of the room.

The shutters (20) and (21) are provided with spring catches (30) and C(31) similar to the catch (18) and adapte to engage openings formed in plates mounted upon the sill to hold the shutters in their closed positions. Additional plates 34k and 35 beupon the outer edges of the sill in position for engagement by said catches 30 and '31 when the shutters are swung open, as shown in Figure 2.

In Figure 7 the guide strip (11) of the sash (6) is provided with a plurality of balls (36) mounted in openings (37) formed in its under face and roviding anti-friction means to facilitate t ie lateral movement of the sash in its groove (14), but ordinarily the strip (11) is constructed of hardwood and the balls are dispensed with.

It is obvious that a window as thus constructed may be readily opened by first rea swinging .613 between leasing the catch (18) and then swinging the sash (7) outwardly upon its hinges (8) and (9) until it lies flat against the sash (6) in which position both sash-members may be moved laterally and centrally positioned within the frame (1) and the shutters then swung inwardly tiereagainst and locked asshown in Figures 2 and 3.

Hinged sash-members constructed in accordance with this invention may be placed in the frame with the break extending horizontally and with the slidably secured sash at the top and the swinging member at the bottom with the one counterbalancing the other, as in a double hung window.

1 claim and desire to secure by Letters Patent of the United States the following: 1. In a casement window, the wmbination with a frame, of a pair of centrally hinged sash-members one of which is adapted for sliding lateral movement in said frame, guidewaysin said frame forming supporting means for one of saidmembers, the other of said members-being free to swing relative thereto and to fold flat therea' inst, and shutters hinged at opposite 'si es' of the.

frame and adapted to be marginally secured to said sash-members when said sash-memhers are in folded relation and central po-- sition.

2. In a casement window, the combination with a frame, of a pair of vertically hinged sash-members one of which is adapted for lateral sliding movement in said frame,

guide-ways formed in said frame, guide strips carried by one of said sash-members and ada ted to en age said guideways, the other 0 said mem ers being free from the frame and adapted to swing horizontally relative to the other sash-member and to fold thereagainst, hinged shutters carried by opposite side edges of said frame and adapted to swing inwardly against said folded sash-members, and fastening means for iecuring said shutters against said memers.

3. In a casement window, the combination with a frame, of apair of vertically bin (1 sash-members one of which is adapted Ti)! sliding movement in said frame, guideways formed in the stile header and sill thereof, guide strips carried by one of said sashmembers and adapted to engage said ideways, the other of said sash-members ing free for horizontal swinging movement rel= ative to said first member and ada ted to fold fiat thereagainst and to be carrie thereby and therewith along said guideway, said thusfolded members being adapted for positionin centrally of the frame to form a central c osed panel with laterally disposed air spaces.

4. In a casement window, the combination with a frame, of a pair of vertically hinged sash-members one of which is adapted or and to be retained therein in slidable relation thereto, the other of said sash-members being free for horizontal swinging move ment relative to said first member and adapted to fold flat thereagainst, said fold- 10 ed members being adapted for positioning centrally of the frame to form a central panel and adjacently disposed air s aces, and hinged shutters carried by said rame and adapted to fold inwardly against said positioned sash-members to screen said air ll spaces.

In testimony whereof I hereunto aifix my signature.
